shaking, use bench for use on four only adjust foot, adjust the balance using the
bubble level.
2) Use independent source, avoid other electrical disturbance.
3) Don´t put any object on the platter when turn on the balance.
4) Please, turn on 2-3 minutes before using.
5) Avoid temperature change too large and air flow strenuous sites.
6) Don´t overload the balance, don´t exceed the maximal capacity.

CONNECT THE LOADCELL TO THE INDICATOR
1) The loadcell connector is 5 pins.
2) When the indicator in power, it is forbidden that take off the loadcell plug, if take
off the plug, the indicator maybe be damaged.
3) It is forbidden that weld the indicator, when there is thunder storm, please make
solution for avoiding the thunder, in this way, it can protect the safe of scales and

BASIC FUNCTION OPERATION
Press and hold this key for 2 seconds to turn off the balance.
Press this key to turn on the balance
To select the desired weight unit.
To reset the weight to zero “0”, but the display value has to be lesser
than ± 2% of maximum capacity.
Function 1. To subtract the container´s weight. Maximum tare: full capacity
Function 2. To preset a tare value. Press this key with empty pan and use
the numerical keys to introduce the desired preset tare weight value, press
again this key to confirm.
To clear the preset tare value, press this key when do not place any object
onto the pan.
To setup the unit weight.
Place the object onto the pan, use 0 – 9 keys and decimal (.) key to input
the piece weight value, then press this key to confirm. The weight window
will show the total weight, the piece weight window will show the piece
weight and the total count window will display the total of pieces.
To setup the sample quantity.
Use 0 – 9 keys to introduce the desired sample quantity, then press this
key to confirm. Weight window will show the weight, piece window will
show the unit weight and the total count window the total of pieces.
To fix a quantity high limit.
Example: Put on the pan the quantity sample, for example 100 units, press
the to confirm and then press the key to fix the limit. Remove
the items from the platter, from now, the balance will beep when the
quantity of pieces placed on the platter arrives to 100pcs.
To accumulate weights and total count, the max accumulation count can
accumulated 99 times
Accumulation function can auto setup, see UF-5 function specification.

Piece weight memory key.
Input piece weight using the 0 – 9 keys, then press this key to memorize
and press the keep where you want to save it, for exemple:
Press this key to select the PLU (M01 – M09) and press again to select the
PLU (M11 – M18)
Press this key to clear the piece weight window.
Press this key to display the total accumulation count, total accumulated
weight and total count.
To clear accumulation data, press and hold this key until buzzer beeps
twice.
